Overview

The sewage treatment aeration membrane microporous aerator consists of an aerator, a gas distribution pipeline, tees, tees, elbows, regulators, connectors, and cleaning devices. The gas pipeline is arranged in a typical circular pattern, with a density based on the gas supply volume and pool shape.

Product Details

1、 Product Introduction

Diaphragm type microporous aeratorIt is a type of aeration device developed in the 1980s, which has a small diameter of aeration bubbles, a small diameter of gas-liquid interface, a large gas-liquid interface area, uniform diffusion of bubbles, and no pore blockage,Sewage treatment aeration membrane microporous aeratorStrong corrosion resistance, tested by the School of Environmental Engineering at Tongji University in Shanghai and the North China Design Institute of Municipal Engineering in China for oxygenation of clean water and sewage, and proven to be effective by over 50 users over the years (reducing energy consumption by 40% or increasing sewage treatment capacity by 40% compared to conventional products such as fixed rotary mixer aerators, diffuser aerators, and aeration hoses). Especially suitable for urban sewage and the construction and expansion of large factories, as well as the renovation of old aeration tanks, and the aeration tanks can operate intermittently.

2、 Main technical parameters:
Aerator size: Φ 200mm, 260mm
Service area: 0.25-0.55m2/piece, 0.35-0.75m2/piece
Average pore size of aeration membrane during operation: 80-100 microns
Air flow rate: 1.5-3m3/h per hour
Total oxygen transfer coefficient: kla (20 ℃) 0.204-0.337min-1
Oxygen utilization rate: (water depth 3.2m) 18.4-27.7%
Oxygenation capacity: 0.112-0.185kgO2/m3h
Oxygenation power efficiency: 4.46-5.19KgO2/kwh
Aeration resistance: 180-280mmH2O
Sewage treatment aeration membrane microporous aeratorThe design of air pipes should consider pressure balance and form a circular network. Each set of intake pipes should be equipped with valves to facilitate the adjustment of air volume. Design flow rate of air pipe: 10-15 meters/second for main pipe; The branch pipe is 5 meters per second. The installation height from the surface to the bottom of the pool is 270mm and 250mm, and the push plate is 200mm.
